Gateway device and method for managing connections on a gateway device
First Claim
1. Gateway device (21) for mounting as an interface between a concentrator (9) of a switched circuit network and a call server (7) of a time-switched network, the concentrator (9) being provided for handling calls of a plurality of subscribers of different access networks (14-16), the gateway device comprising a series of gateway units (22a-c), each having a media gateway (24a-c) and a first (22a) having a first signalling gateway (23a), each media gateway (24a-c) comprising a number of resources for connecting calls between the concentrator (9) and the call server (7), characterised in that the first signalling gateway (23a) comprises:
- memory means for storing assignment data about the resources of each of the media gateways (24a-c), means (6) for receiving a call initiation signal associated with an incoming call originating from any of the subscribers of any of the access networks (14-16), means for selecting and assigning an available resource of any of the media gateways (24a-c) to the incoming call based on the assignment data stored in the memory means, means for storing the assignment of the resource to the incoming call in the memory means, means (5) for receiving a call termination signal associated with a terminated call, means for deleting the assignment of the resource to the terminated call from the memory means.

4. Method for managing connections on a gateway device (21) mounted as an interface between a concentrator (9) of a switched circuit network and a call server (7) of a time-switched network, the concentrator (9) being provided for handling calls of a plurality of subscribers of different access networks (14-16), the gateway device (21) comprising a series of gateway units (22a-c), each having a media gateway (24a-c) and a first (22a) having a first signalling gateway (23a), each media gateway (24a-c) comprising a number of resources for connecting calls between the concentrator (9) and the call server (7), characterised in that the method comprises the steps of:
-
a) storing assignment data about the resources of each of the media gateways (24a-c) in memory means provided on the first signalling gateway (23a), b) communicating a call initiation signal associated with an incoming call originating from any of the subscribers of any of the access networks (14-16) from the concentrator (9) to the first signalling gateway (23a), c) selecting and assigning an available resource of any of the media gateways (24a-c) to the incoming call based on the assignment data stored in the memory means, d) storing the assignment of the resource to the incoming call in the memory means, e) communicating a call termination signal associated with a terminated call from the call server (7) to the first signalling gateway (23a), f) deleting the assignment of the resource to the terminated call from the memory means. - View Dependent Claims (5, 6, 7)
